DETAILED DESCRIPTION OF THE INVENTION

Compounds of Formula I are prepared by the procedure of Equation 1 wherein L, R, X, Y and Z are as previously defined. This procedure is well known in the art. ##STR7##

The reaction is best carried out in inert aprotic organic solvents such as methylene chloride, tetrahydrofuran or acetonitrile, at ambient pressure and temperature. The mode of addition is not critical; however, it is often convenient to add the sulfonyl isocyanate to a stirred suspension of the aminotriazine. Since such isocyanates usually are liquids, their addition is more easily controlled.

The reaction is generally exothermic. In some cases, the desired product is insoluble in the warm reaction medium and crystallizes from it in pure form. Products soluble in the reaction medium are isolated by evaporation of the solvent, trituration of the solid residue with solvents such as 1-chlorobutane, ethyl ether, or pentane, and filtration.

The intermediate sulfonyl isocyanates of Formula II can be prepared by reacting corresponding sulfonamides with phosgene in the presence of n-butyl isocyanate at reflux in a solvent such as chlorobenzene, according to the procedure of H. Ulrich and A. A. Y. Sayigh, Newer Methods of Preparative Organic Chemistry, Vol. VI, pages 223-241, Academic Press, New York and London, W. Foerst Ed. In cases where formation of the desired sulfonyl isocyanate is difficult by the above procedure the sulfonylurea formed by reaction of butyl isocyanate with the appropriate sulfonamide is treated with phosgene according to the above reference.

Alternatively, compounds of Formula I can be prepared by contacting a sulfonyl carbamate of Formula IV with amine III as shown in Equation 2. ##STR8##

The reaction is carried out at 50° to 100° C. in a solvent such as dioxane for 0.5 to 24 hours as taught in EP-A-44,807. The required carbamates IV are prepared by contacting the corresponding sulfonamides V with diphenylcarbonate or phenylchloroformate in the presence of base.

The compounds of Formula I can also be prepared by contacting a sulfonamide of Formula V with an O-phenylcarbamate of Formula VI in the presence of base as shown in Equation 3. ##STR9##

The reaction is carried out at 0° to 50° C. in an inert solvent such as acetonitrile for 0.1 to 24 hours in the presence of a base such as 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) as taught in EP-A-44,807. The required carbamate VI is prepared by reacting amine III with diphenylcarbonate or phenylchloroformate in the presence of base.

The sulfonamides used as intermediates for this invention can be prepared by methods known in the art. The preparation of LSO₂ NH₂ where L is L-1 can be prepared as taught in U.S. Pat. Nos. 4,127,405; 4,310,346 or 4,435,205. When L is L-3, L-4 or L-5, methods such as those referred to in EP-A-64,804 and U.S. Pat. No. 4,398,939 can be used for the preparation of the sulfonamide intermediates. Naphthalenesulfonamides (L is L-2) can be prepared according to procedures referred to or described in U.S. Pat. No. 4,370,479. Sulfonamides where L is L-6, L-7, L-8, L-9 or L-10 can be prepared as described in EP-A-107,979.

Aminotriazines of structure III can be prepared by methods described in EP-A-9,419 (published Apr. 2, 1980). Pyrimidine intermediates of structure III can be prepared by similar procedures by substituting an appropriately substituted pyrimidine for triazines used in the procedures referred to above.

Agriculturally suitable salts of compounds of Formula I are also useful herbicides and can be prepared in a number of ways known to the art. For example, metal salts can be made by contacting compounds of Formula I with a solution of an alkali or alkaline earth metal salt having a sufficiently basic anion (e.g., hydroxide, alkoxide, carbonate or hydroxide). Quaternary amine salts can be made by similar techniques.

Salts of compounds of Formula I can also be prepared by exchange of one cation for another. Cationic exchange can be effected by direct contact of an aqueous solution of a salt of a compound of Formula I (e.g., alkali or quaternary amine salt) with a solution containing the cation to be exchanged. This method is most effective when the desired salt containing the exchanged cation is insoluble in water and can be separated by filtration.

Exchange may also be effected by passing an aqueous solution of a salt of a compound of Formula I (e.g., an alkali metal or quaternary amine salt) through a column packed with a cation exchange resin containing the cation to be exchanged for that of the original salt and the desired product is eluted from the column. This method is particularly useful when the desired salt is water-soluble.

Acid addition salts, useful in this invention, can be obtained by reacting a compound of Formula I with a suitable acid, e.g., p-toluenesulfonic acid, trichloroacetic acid or the like.

The compounds of this invention and their preparation are further illustrated by the following examples wherein temperatures are given in degrees centigrade.

EXAMPLE 1 2-Amino-4-(2,2,2-trifluoroethoxy)-6-methoxy-1,3,5-triazine

A. A solution of 300 g (1.63 mol) of cyanuric chloride in 1 liter THF and 0.24 liter diglyme was cooled to 0° C. and 81.6 mL (3.36 mol) of liquid ammonia added dropwise over 90 min. keeping the temperature between 10°-15°. The mixture was stirred for one hour at -10° to 0° and then allowed to warm to ambient temperature over one hour. The resulting suspension was filtered, the solid washed with THF, the filtrate reduced to 1/2 its original volume, and poured over 1 liter of ice water to give a white solid which was collected, washed with water, and dried in vacuo to give 244.3 g of 2-amino-4,6-dichloro-1,3,5-triazine with m.p. 221°-223.5° (dec).

B. To a suspension of 50.0 g (0.3 mol) of 2-amino-4,6-dichloro-1,3,5-triazine in 600 mL of methanol was added portionwise 19.5 g (0.3 mol) of 85% potassium hydroxide pellets with the temperature being kept between 15°-20°. The resulting suspension was stirred at 10°-15° for one hour and then allowed to warm to room temperature over 1.5 hours. The white solid was collected, washed three times with water, and dried in vacuo to give 37.1 g of 2-amino-4-chloro-6-methoxy-1,3,5-triazine with m.p. 221°-223.5° (dec).

C. To a suspension of 10.0 g (0.06 mol) of 2-amino-4-chloro-6-methoxy-1,3,5-triazine and 6.2 g (0.06 mol) of 2,2,2-trifluoroethanol in 150 mL of methylene chloride was added portionwise over five minutes 4.1 g (0.06 mol) of 85% potassium hydroxide pellets. After an initial exotherm to 27° the reaction mixture was stirred at ambient temperature overnight. The suspended solid was removed by filtration and filtrate concentrated in vacuo to give 13.21 g of white solid with m.p. 77°-80°. This was recrystallized from n-butyl chloride to give 11.16 g of 2-amino-4-(2,2,2-trifluoroethoxy)-6-methoxy-1,3,5-triazine as a white powder with m.p. 78°-80°.

Formulations

Useful formulations of the compounds of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly. Sprayable formulations can be extended in suitable media and used at spray volumes of from a few pints to several hundred gallons per acre. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 1-99% by weight of active ingredient(s) and at least one of (a) about 0.1-20% surfactant(s) and (b) about 5-99% solid or liquid diluent(s). More specifically, they will contain these ingredients in the following approximate proportions:

Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing.

Typical solid diluents are described in Watkins, et al., Handbook of Insecticide Dust Diluents and Carriers, 2nd Edition, Dorland Books, Caldwell, NJ. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, Solvents Guide, 2nd Edition, Interscience, New York 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0° C. McCutcheon's Detergents and Emulsifiers Annual, Allured Publishing Corp., Ridgewood, NJ, as well as Sisely and Wood, Encyclopedia of Surface Active Agents, Chemical Publishing Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foam, caking, corrosion, microbiological growth, etc. Preferably, ingredients should be approved by the U.S. Environmental Protection Agency for the use intended.

The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, U.S. Pat. No. 3,060,084). Granules and pellets may be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See J. E. Browning, "Agglomeration" Chemical Engineering, Dec. 4, 1967, pages 147ff and Perry's Chemical Engineer's Handbook, 4th Edition, McGraw-Hill, New York 1963, pages 8-59ff.

The ingredients are blended and milled to pass through a 100 mesh screen. This material is then added to a fluid bed granulator, the air flow is adjusted to gently fluidize the material, and a fine spray of water is sprayed onto the fluidized material. The fluidization and spraying are continued until granules of the desired size range are made. The spraying is stopped, but fluidization is continued, optionally with heat, until the moisture in the material is reduced to the desired level, generally less than 1%. The material is then discharged, screened to the desired size range, generally 14-100 mesh (140-149 microns), and packaged for use.

The ingredients are blended, hammermilled and then moistened with about 12% water. The mixture is extruded as cylinders about 3 mm diameter which are cut to produce pellets about 3 mm long. These may be used directly after drying, or the dried pellets may be crushed to pass a U.S.S. No 20 sieve (0.54 mm openings). The granules held on a U.S.S. No. 40 sieve (0.42 mm openings) may be packaged for use and the fines recycled.

UTILITY

Test results indicate that the compounds of the present invention are active herbicides. They should have utility for broad spectrum pre- and/or post-emergence weed control in areas where complete control of all vegetation is desired, such as around fuel storage tanks, ammunition depots, industrial storage areas, parking lots, drive-in theaters, around billboards, highway and railroad structures. Alternatively, the subject compounds are useful for the selective pre- or post-emergence weed control in corn.

The rates of application for the compounds of the invention are determined by a number of factors, including their use as selective or general herbicides, the crop species involved, the types of weeds to be controlled, weather and climate, formulations selected, mode of application, amount of foliage present, etc. In general terms, the subject compounds should be applied at levels of around 0.002-5 kg/ha, the lower rates being suggested for use on lighter soils and/or those having a low organic matter content, for selective weed control or for situations where only short-term persistence is required.

The compounds of the invention may be used in combination with any other commercial herbicide; examples of which are those of the triazine, triazole, uracil, urea, amide, diphenylether, carbamate, and bipyridylium types. They may also be used in combination with mefluidide.

TEST A

Seeds of crabgrass (Digitaria spp.), barnyardgrass (Echinochloa crusgalli), wild oats (Avena fatua), sicklepod (Cassia obtusifolia), morningglory (Ipomoea spp.), cocklebur (Xanthium pensylvanicum), sorghum, corn, soybean, cotton, sugar beet, rice, wheat, and purple nutsedge (Cyperus rotundus) tubers were planted and treated preemergence with the test chemicals dissolved in a nonphytotoxic solvent. At the same time, these crop and weed species were treated with a soil/foliage application. At the time of treatment, the plants ranged in height from 2-18 cm. Treated plants and controls were maintained in a greenhouse for sixteen days, after which all species were compared to controls and visually rated for response to treatment. The ratings, summarized in Table A, are based on a numerical scale extending from 0=no injury, to 10=complete control. The accompanying descriptive symbols have the following meanings:

C=chlorosis/necrosis

E=emergence inhibition

G=growth retardation

H=formative effect

The herbicidal properties of the subject compounds were discovered in a number of greenhouse tests. The test procedures and results follow:

TEST B

Postemergence

Two round pans (25 cm diameter by 12.5 cm deep) were filled with Woodstown sandy loam soil. One pan was planted with blackgrass (Alopecurus myosuroides), sugar beets, nutsedge (Cyperus rotundus) tubers, crabgrass (Digitaria sanguinalis), sicklepod (Cassia obtusifolia), teaweed (Sida spinosa), jimsonweed (Datura stramonium), velvetleaf (Abutilon theophrasti), and giant foxtail (Setaria faberii). The other pan was planted with wheat, cotton, rice, corn, soybean, wild oats (Avena fatua), cocklebur (Xanthium pensylvanicum), morninglory (Ipomoea hederacea), johnsongrass (Sorghum halepense) and barnyard grass (Echinochloa crusgalli). The plants were grown for approximately fourteen days, then sprayed postemergence with the chemicals dissolved in a nonphytotoxic solvent.

Preemergence

Two round pans (25 cm diameter by 12.5 cm deep) were filled with Woodstown sandy loam soil. One pan was planted with blackgrass (Alopecurus myosuroides), sugar beets, nutsedge, crabgrass, sicklepod, teaweed, jimsonweed, velvetleaf, and giant foxtail. The other pan was planted with wheat, cotton, rice, corn, soybeans, wild oats, cocklebur, morningglory, johnsongrass and barnyardgrass. The two pans were sprayed preemergence with the chemicals dissolved in a nonphytotoxic solvent.

Treated plants and controls were maintained in the greenhouse for 28 days, then all treated plants were compared to controls and visually rated for plant response as described for Test A.

Response ratings are contained in Table B. The data show that both test compounds have utility for selective pre- and postemergence weed control in corn.

TEST C

Three 25-cm diameter plastic pots were filled with a light soil. One pot was planted to short rows of corn, soybeans and cotton, planting depth 2.5 cm. The other two pots were plants to the following weed species, 8 or 9 species per pot: crabgrass (Digitaria sp.), johnsongrass (Sorghum halepense), barnyardgrass (Echinochloa crusgalli), nutsedge (Cyperus rotundus), giant foxtail (Setaria faberi), green foxtail (Setaria viridis), cocklebur (Xanthium pensylvanicum), morningglory (Ipomoea hederacea), teaweed (Sida spinosa), sicklepod (Cassia obtusifolia), jimsonweed (Datura stramonium), velvetleaf (Abutilon theophrasti), bindweed (Convolvulus arvensis), coffeeweed (Sesbania exaltata), lambsquarters (Chenopodium album), pigweed (Amaranthus retroflexus) and purslane (Portulaca oleracea). All of the foregoing weed species were planted at a depth of 0.5-1.0 cm except for cocklebur and nutsedge which were planted at a depth of 2.5 cm. The plantings were treated preemergence with the test chemicals dissolved in a nonphytotoxic solvent. At the same time, the same crops and weed species, from plantings made 10-21 days previously, were treated with soil/foliage applications. Treated plants and controls were maintained in a greenhouse for 3-4 weeks after which all species were compared to controls and visually rated for response to treatment utilizing the same rating system as described for Test A. The data for three tests for Compound 1 and two tests for Compound 2 are summarized in Table C.

It will be seen that both compounds can be used for selective weed control in corn, either applied pre- or postemergence.

TEST D

This test was conducted utilizing 25 cm and 12.5 cm diameter pots filled with a light soil. The large size pots were planted to either corn or soybeans, 5-8 plants per pot. The small pots were planted to the following weed species, one species per pot: morningglory (Ipomoea hederacea var. hederacea), velvetleaf (Abutilon theophrasti), cocklebur (Xanthium pensylvanicum), pigweed (Amaranthus retroflexus), giant foxtail (Setaria faberi), johnsongrass (Sorghum halepense), crabgrass (Digitaria sp.) and barnyardgrass (Echinochloa crusgalli). The plants were treated preemergence with the test chemical dissolved in a nonphytotoxic solvent. At the same time, the same crops and weed species, from plantings made 10-22 days previously, were treated with soil/foliage applications. There were three replications of each treatment. Response data were collected approximately 17 days after treatment for the postemergence phase of the test and approximately 27 days after treatment for the preemergence phase. The weed species were visually rated for injury. The crop plantings contained an equal number of plants per pot for each crop. At the time of rating, total fresh weights per pot were determined of the above-ground portions of the crop plants. Growth since treatment was then calculated and expressed as a percentage of untreated controls. The response data were averaged for the three replications and are shown in Table D.

Compound No. 1 controlled several weed species at rates of application which were noninjurious to corn.
